quality

quality is a skill for Claude Code, Codex from gullitmiranda/.cursor. It costs 54 tokens per session (1,491 once invoked), scanned A, original, MIT.

A set of rules for code quality, commits, pull requests, documentation, performance, security, and clean text output.

In plain words
What is it for?
Use it while writing code, preparing commits or pull requests, documenting work, checking performance and security, or cleaning generated text.
Why use it?
It provides consistent checks for common problems, such as unclear code, invalid commit messages, missed tests, security issues, or invisible characters.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

quality scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quality Rules

MANDATORY — Output hygiene: Never use gremlin/invisible characters in any generated text. Use only standard space (U+0020) and normal line breaks (LF/CRLF). No zero-width (U+200B, U+200D, U+200C), no non-breaking space (U+00A0) unless required, no control or separator characters (U+2028, U+2029). Rewrite pasted content as clean text instead of copying raw.

Code Quality

Commit Standards

  • Use conventional commit format: <type>(<scope>): <description>
  • Types: feat, fix, chore, docs, style, refactor, test
  • Present tense, imperative mood
  • Always write commit messages in English
  • Include Linear issue references when applicable
  • Keep descriptions concise but descriptive

Code Style

  • Follow project-specific linting rules
  • Maintain consistent code style across the project
  • Use meaningful variable and function names
  • Include proper error handling
  • Write clear, self-documenting code
  • Add comments for complex logic

Lint and format fix workflow (Trunk)

When fixing lint, format, or style issues in a project that uses Trunk:

  1. First: Run trunk check --fix to auto-fix everything Trunk can fix.
  2. Then: Address any remaining issues manually (what Trunk reports but could not auto-fix).
  3. Re-run trunk check (or trunk check --fix) to confirm all issues are resolved.

Do not manually fix what Trunk can fix; let Trunk do it first, then the agent resolves the rest.

Code Organization

  • Keep functions small and focused
  • Use appropriate design patterns
  • Maintain clear separation of concerns
  • Follow DRY (Don't Repeat Yourself) principles
  • Organize imports and dependencies properly

Quality Gates

Pre-commit Checks

  • All tests must pass before committing
  • Linting must pass without errors
  • Build must succeed
  • Security scans must pass
  • No sensitive data in commits

Pre-PR Checks

  • All quality gates must pass
  • Code review requirements met
  • Documentation updated
  • Tests cover new functionality
  • Performance impact assessed

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
